Lisset was an agent of the Spirit of the Abyss sent to retrieve the Voice of Darkness. Hoping to find clues to the Voice's whereabouts, she ventured to the Collectors Virtual Library Archives on Daedalus V with a massive datanet virus, designed to scan and erase every single one of Library's virtual reality simulations. Just as Lisset and her datanet were searching the library, Seamus Harper came out of his program and was Lisset forced to hide. As Dylan, Beka, and Harper went back into their simulations to find clues, she reappeared, to find Rhade standing guard. The two fought hand to hand, however, due to Lisset's tremendous physical strength, Rhade was no match for her, and ended be thrown across the room, allowing her the time she needed to hide yet again. Lisset then fled into Dylan and Amira's program; once inside, she tried to force them to give her the Voice of Darkness, threatening them and the library if they did not comply. However, Dylan and Amira refused too give it to her, and a fight broke out at the same time the program resumed, Lisset playing the part of a Nietzschean that originally attacked Wezlow and Nema. The Nietzschean killed Nema, and at that moment Amira revealed the Voice Lisset had been searching for, using it to incapacitate her. Amira and Dylan escaped the program, leaving Lisset inside. Once back in the physical world, Dylan broke the flexi key, thus leaving her trapped in a continual loop within the archives.

Lisset was shown to have an tremendous amount of physical power, allowing her to not only beat Rhade in a fight, but to knock him unconscious by throwing him clear across the room. It is unknown whether this strength was a gift from her master, the Abyss, or is related to her own natural physiology. In addition she wore a small black amulet around her neck which she used to direct her massive datanet. ("Time Out of Mind")
